Early Diagnosis of Necrotizing Fasciitis by Utilization of Ultrasonography

壞死性筋膜炎是一種少見而且病理過程進展很快的筋膜組織發炎，因為早期皮膚並無明顯病變故往往造成診斷上的困難。本篇文章探討五位懷疑是壞死性筋膜炎的病人，利用超音波檢查診斷，再以手術組織切片檢查來確認病人的診斷，五位病人中經由組織切片檢查有三位確認是壞死性筋膜炎，二位為蜂窩組織炎。壞死性筋膜炎超音波檢查的發現有三：（1）筋膜層呈現不規則狀；（2）在筋膜層的表層有不正常液體聚集；（3）筋膜層有廣泛性的增厚，在二位蜂窩組織炎的病患，其超音波檢查，並無上列的發現，我們研究顯示，超音波檢查對壞死性筋膜炎的早期診斷有正面的幫助。

Necrotizing fasciitis is a rare and rapid progression soft tissue infection. The only identifiable feature is tissue necrosis along a single fascia plane. Because the skin is initially spared, it is difficult for early recognition prior to extensive tissue destruction. Ultrasonography was used for early diagnosis of this infection in five cases. All 5 patients presented with severe cellulitis. Under the suspicion of necrotizing fasciitis, ultrasonography was performed before surgical debridement. Tissue biopsy was done for histological confirmation of the diagnosis. Three patients were proven to have necrotizing fasciitis and two cellulitis only. The ultrasonographic findings of necrotizing fasciitis included: 1) irregularity of the fascia; 2) abnormal fluid collections along the fascia plane; and 3) diffuse thickening of the fascia when compared with the control site in the normal limb. However, in severe infectious cellulitis, the above mentioned findings were not observed. Our results indicate the usefulness of the ultrasonography for early diagnosis of necrotizing fasciitis.
